As Japan's most highly integrated refiner, TonenGeneral is a superior supplier of high-quality petroleum products and petrochemicals.
The oil industry is made up of several segments, from exploration, development and production of crude oil (upstream businesses) to refining, transportation and marketing of petroleum products (downstream businesses). The TonenGeneral Group's main business fields are oil, centered on the downstream area, and chemicals, centered on manufacturing, processing and marketing of petrochemicals. We aim to maximize added value through integration of planning and operations between the segments.
